Cybersecurity (Senior) Software Engineer (m/w/d)

YOUR TASKS You develop secure software and infrastructure solutions and integrate security-by-design principles into the development and deployment process from the very beginning. You support our clients in the design, development, and protection of modern applications and infrastructures, for example in the areas of AI, web, APIs, and cloud. You identify security risks in existing applications, cloud environments, and infrastructure configurations and derive concrete measures to remediate them. You conduct code reviews with a focus on security and establish best practices for secure software development. You work closely with development teams, architects, infrastructure teams, and security stakeholders to design secure systems holistically. You implement security mechanisms such as authentication, authorization, encryption, and secrets management in software solutions and cloud configurations. You integrate security checks into CI/CD pipelines and support the development of DevSecOps structures. You develop and maintain infrastructure-as-code solutions to provision cloud and platform infrastructures securely, transparently, and repeatably. You analyze new technologies and tools in the field of application security and actively contribute your ideas to client projects. You support our clients in their transformation toward secure software development, modern architectures, and automated infrastructure processes. You take ownership of your own work packages and actively contribute to the further development of our topics and services.
